FEED-WATER HEATER FOR LOCOMOTIVES.

SPECIFICATION formingpart of Letters Patent No. 279,383,dated June 12, 1883.

Application filed February 13, 1883. (No model.) i

To aZZ whom it may concern:

Be it known that I,HENRY HEATON, of Cleve land, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Heating Feed-Water for Locomotives; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to feed-water heaters, and more especially to hea'ters as applied to locomotive-engines; and it consists of certain features of construction and combinations of parts, hereinafter described, and pointed out in the claims.

In the drawings, Figure 1 is a side elevation, and Fig. 2 a plan view, of a heater and so much of the locomotive-engine audits attachments as are needed to illustrate my invention. Fig. 3 is an end view of the cylinders and heater, and showing also the exhaust-pipes leading from the cylinders to the heater. Fig.

4. is a longitudinal section of the heater, and

Fig. 5 is a transverse section thereof.

v A represents the boiler of a locomotive-en. gine; B B, the cylinders; O, the heater, and D the water-tank located in the tender.

The pipes 12 conduct the exhaust-steam from the cylinders to the heater, and the pipe 6' conveys the remainder of the exhaust-steam that is not condensed in the heater to the tank D; and (2 represents a coil of pipe that is a continuation of the pipe 0 and immersed in the water of the tank. These coils are to be of such condensing capacity as to condense all of the remaining exhauststeam that comes from the heater. The feed-water is taken from the water-tank on the tender aforesaid through the pipe F, and is forced by means of pumps, injectors, inspirators, or other devices through a pipe or pipes, 0, within the heater, and thence into the boiler.

The pipe E, through which the water passes from the heater to the boiler, is on the end of the heater that is nearest to the cylinders, and consequently at that end of the heater where the exhauststeam is the hottest, while the pipe F, through which the water is forced from the tank into theheater, enters the heater at the end that is farthest from the cylinder that is to say, the coolest end of the heater.

The operation of my device is as follows: The water when taken from the tank, if the engine has been running for a short time, is already quite warm from two causes, first, from the heat from the coil (1, wherein the con densation of the exhaust-steam is completed; and, second, the condensed water that is discharged from the heater and the said coil of pipe (1 is at but little less than the boilingpoint. This warm water then is forced through the heater, commencing at the end of the heater where the exhaust-steam is the coolest, and follows through the pipes G in the heater in the opposite direction from that in which the exhaust-steam that is surrounding the pip es is traveling. The result is that the feed-water rapidly increases in temperature as it passes along the heater, and till just asit is leaving the heater to enter the boiler the pipes containing the said feed-water are exposed to the action of the hot steam direct from the cylinders striking against the said pipes, causing the feedwater to be raised to a very high temperature 7 5 as it goes to the boiler.

I do not limit myself to the construction herein described, or shown in the drawings, .as-N

a variety of ways might be employed for accomplishing the same object.

What I claim is l. The combination, with the cylinders B B, tank D, steam-pipe c, and water-supply pipes E F, of the heater 0, provided with pipes C, and pipes b 7) leading thereto, substantially as set 85 forth.

2. The combination, with the cylinders B B, tank D, coil d, steampipe c, and water-supply pipes E F, of the heater 0, provided with pipes C, and pipes b b, substantially as set forth.

In testimony whereof I sign this specification, in the presence of two witnesses, this 23d day of January, 1883.

HENRY HEATON.
